jjeff said:For about $12 you could purchase a OBDII adapter(assuming you don't have a iPhone but do have a android phone) and download the free Leafspy lite app and you could read your cars SOH. Of course living where you do I'd bet you'd have other Leaf drivers not too far away who might not mind uplugging their OBDII, plugging it in your car and giving you the reading, it's up to you.
Personally with a '11 or '12 Leaf I wouldn't want to be without either Leafspy or some other dedicated battery health reader. If not for the battery health then for the very handy SOC% display that personally I wouldn't want to live without.
This is the OBDII I have and it works very well with a Samsung Galaxy smart phone:

I purchased a similar configured ELM327 V2.1 that has the same ISO spec compliance, but does not have the SAE J1850 PWM (41.6 Kbaud)
SAE J1850 VPW (10.4 Kbaud) compliances listed. Don't believe this is the issue, just an observation.
They are the same size and color with a different label. I could not get it to recognize the ECU. I'm surprised that these chinese clones are any different (except the label) - however, they must be.
Turbo3 has a good explanation (he should know) about how the Leaf has slightly different protocols and unless the dongle is fully compliant with V1.5ELM327, it might not work.
The incompatibilities go on.
